What is the regulatory provision for occupational exposure of a declared pregnant woman per month?

• A. 0.5 mrem
• B. 0.05 rem
• C. 0.05 mrem
• D. 0.5 rem

Answer: (B)

Protecting the developing fetus drives the limit for a declared pregnant worker. The regulatory goal is to keep fetal dose well below levels that could cause harm, with the entire pregnancy limited to about 0.5 rem. To ensure this, the monthly occupational exposure to the fetus is capped at 0.05 rem per month. That’s 50 mrem each month, roughly 0.5 mSv. Over a typical nine-month pregnancy, this totals around 0.45 rem, staying under the 0.5 rem fetal limit. So the per-month limit is 0.05 rem.
